What it is
dHCI combines two approaches: the flexibility of a classic three-tier architecture, where storage, servers and network grow independently, and the vCenter-integrated management of a hyperconverged platform. All of it driven from the browser.
Compute is a ProLiant of your choice; storage is an HPE Alletra 6000.
Why it is worth it
The practical gain is the update. Through its link to HPE InfoSight, the compatibility checking before a system update goes away: server firmware, drivers, ESXi and the Alletra operating system are updated together in one controlled run.
Anyone who has checked a matrix of four version levels by hand knows how much work that is.
What it is for
Estates that want HCI’s simplicity but are not willing to buy compute and capacity in the same step. That is exactly where classic HCI gets expensive, because you buy one to get the other.
